See the code in CloneFunctionInto and CloneAndPruneFunctionInto. This is
what does the actual inlining. You can see how that code tracks the basic
blocks after inlining.

Honestly, the right way to do this architecturally is for us to support
metadata attached to basic blocks (if we don't already?) and then for the
inliner to preserve it when inlining. Then you could use metadata as a
container for your data.
